AIR-COMPRESSOR.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed June 6, 1908. Serial No. 437,095.

To all whom it may concern:

Be it known that I, HARRY E. BAILEY, a

citizen of the United States, and a resident of Albany, in the county of Albany and State of New York, have invented a new and Improved Air-Compressor, of which the following is a full, clear, and exact description.

The invention relates to hydraulic air compressors employed for supplying air pressure to kegs, barrels or other receptacles containing beercand other liquids to be elevated to a dispensing faucet or the like.

The object of the invention is to provide a new and improved air compressor which is simple and durable in construction, not liable to leak or to get out of order, and arranged to prevent the water from accidentally passing into the receptacle filled with beer or other liquid.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the improvement; Fig. 2 is a plan view of thesame, the casing body being removed and parts being in section; Fig. 3 is an enlarged sectional side elevation of the improvement showing the parts in a different position from the one shown in Fig. l; and Fig. 4 is an "enlarged transverse section of the same on the line 4ll of Fig. 3.

The casing A is provided at its bottom with a water inlet B connected with a street main or other suitable source of water supply, and in the water inlet pipe B is arranged a reducing valve G of the usual construction. The water inlet pipe B terminates within the casing A on an upright, slightly tapering valve seat D (see Fig. A), adapted to be engaged by a disk valve E having a tapering face, and provided with a stem E slidable in one end of a lever F fulcrumed at F on a bracket G attached to the bottom of the casing A, as plainly shown in the drawings. The end of the valve stem E is engaged by a set screw E screwing in the lever F, to permit the operator to adjust the face of the disk valve E relative to the face of the valve seat D to insure accurate seating of the disk valve E on the seat D, to prevent water from passing into the casing A at the time the disk valve E is seated on the valve seat D. The lever F carries another disk valve I-I adapted to be seated on a horizontally-arranged valve seat H leading to the water discharge pipe 11 for carrying the water to a suitable place of discharge. Now by the arrangement described, the valve seats D and H stand approximately at a right angle one to the other, and when the casing A is emptied the disk valve E is opened while the disk valve H is closed, as shown in Figs. 1 and 8, and when the casing A has filled with water and a swinging motion is iven to the lever F, as hereinafter more fully explained, then the valve H swings into an open position while the valve E moves into a closed position on the valve seat D, to shut off the water from the casing A. Then the valve H is opened the water flows out of the casing by way of the valve seat H and the water outlet H In order to impart a swinging motion to the valve lever F the following arrangement is made: On the valve lever F is formed an arm F adapted to be alternately engaged on opposite sides by the free ends of arms I, I held on a lover I, fulcrumed at I on the bracket G. The lever I is provided with a weight I and with a transverselyextending cam I adapted to be alternately engaged on opposite sides by friction rollers J J 2 held on a float lever J fulcrumed at J 3 on the bracket G and provided with a float J 4 rising and falling with the water in the casing A.

The cam I of the weighted lever I is provided with an extension I (see Figs. 2 and 4), adapted to engage a rod K depending from a valve lever K fulcrumed at K on the air supply pipe L attached to the bottom of the casing A and extending therein nearly to the top thereof, the lower outer end of the air inlet pipe L having a contracted entrance L through which passes the air into the pipe L and from the latter into the casing A at the time the water recedes therein. The valve K on the valve lever K is preferably in the form of a screw screwing in the lever K and adapted to be seated on the top or upper end of the air inlet pipe L. An air outlet pipe N leads from the top of the casing A, and on its entrance end is arranged a cage 0 containing a float valve P adapted to rise only to close the air outlet N in case the water should accidentally rise in the casing to the top thereof, so that the water is prevented from passing through the air outlet N to the receptacle containing the liquid to be elevated, it being understood that the air outlet N is connected with the said receptacle in the usual manner.

The operation is as follows: When the several parts are in the position shown in Fig. 1, the float J 4 is in a lowermost position, and the valve E is opened while the valves H and K are closed. ater can now enter the casing A through the water inlet B and open valve seat D to fill the casing, the water in rising within the casing causing the float J* to rise, and the friction roller J finally engages with the cam 1 so as to impart a swinging motion to the weighted lever I in the direction of the arrow a. The weight 1* of the lever I finally passes a central position and in doing so it suddenly swings into a lowermost position to the left, whereby the arm I engages and pushes the arm 1? from the left to the right, thus imparting a swinging motion to the lever F to open the valve H and to close the valve E. The water in rising in the casing A, as above described, compresses the air therein and forces .the air through the outlet N into the receptacle or other place in which the air pressure is wanted. The weighted lever I in swinging over into the left-hand position causes the opening of the air inlet pipe L by the action of the cam I on the arm K (see dotted lines in Fig. 3), so that air can now pass into the casing A by way of the pipe L, while return flow of the air by way of the pipe N is prevented byasuitable check valve (not shown). hen the valve H swings open and the valve E is moved into a closed position then the flow of the water into the casing is cut oif while the water within the casing can flow through the water outlet H to a suitable place of discharge. The fioat J descends with the falling water within the casing A, so that the friction roller J finally engages the cam I and imparts a return swinging motion to the lever I in the inverse direction of the arrow 0/. When the weight I of the lever I now passes a central position at the time the fioat J is in a lowermost position and the water has escaped from the casing A, then the lever I suddenly swings downward into a right-hand side position, thus causing the arm I to act on the arm F with a view to impart a swinging motion to the lever F, thereby moving the disk valve H into a closed position and the valve E into an open position; at the same time the valve lever K swings back into a closed position to close the upper end of the air inlet pipe L. The above-described operation is again repeated, that is, water again enters the casing A by Way of the water inlet B and the valve seat D, to compress the air contained in the casing A and to discharge the compressed air by way of the air outlet N, and when the water has reached a predetermined level, the weight I of the lever I has passed a central. position, thus causing the swinging over of the lever 1 into a left-hand position, to again change the position of the lever F carrying the disk valves E and I-l.

From the foregoing it will be seen that the operator is enabled to accurately adjust the disk valve E, so as to bring the faces of the valve E and the valve seat D in firm contact with each other at the time the valve E moves into a closed position, so that water may not pass into the casing A during the time the valve H is open and consequently water is not wasted.

By providing the pipe L with the contracted inlet end L dust and other impurities are prevented from passing into the casing A, thus avoiding clogging up of the mechanism arranged within the casing, and by having the cage 0 and the valve P, water is prevented from passing into the air outlet pipe N in case the water should accident-ally rise in the casing A beyond its predeter mined level.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l.
